  FIG. 1 is a schematic view showing a housing and a door in which a hinge device for an opening and closing door (hereinafter, abbreviated as a hinge device) according to an embodiment of the present invention is incorporated. FIG. 2 is a schematic configuration of the hinge device of the present invention. FIG. The same parts as those in the conventional hinge device shown in FIGS. 7 and 8 are denoted by the same reference numerals, and detailed description of the overlapping parts will be omitted.

  As shown in FIG. 1, a housing 1 that stores various articles including electronic devices is provided with a door 3 that opens and closes an opening 2 of the housing 1. A hinge device 20 for connecting the housing 1 and the door 3 is provided. The hinge device 20 includes a fixed member 21 having one end fixed to the peripheral edge 5 of the opening 2 of the housing 1, and a rotating member 8 having one end fixed to the inner surface 7 of the door 3. .

  FIG. 2 is an exploded perspective view illustrating a schematic configuration of the hinge device 20. In the fixed-side member 21, the support portion 11 is integrally formed with the substrate 10 fixed to the peripheral edge 5 of the opening 2 of the housing 1 with fixing screws 9a and 9b. In a cylindrical portion 22 formed at the tip of the support portion 11, a through-hole 23 that penetrates vertically through the cylindrical portion 22 is formed. A female screw is formed in the through hole 23.

  A bolt 24 is screwed into this through hole 23 so as to be vertically movable. The upper end and the lower end of the bolt 24 are exposed above and below the through hole 23. Nuts 27 and 28 are provided at upper and lower exposed portions of the bolt 24 to sandwich and clamp the through hole 23 from above and below. Further, a receiving hole 26 that opens upward is formed in the head 25 at the upper end of the bolt 24.

  On the other hand, in the rotation side member 8, an axial pin 16 is provided to project downward from the lower surface of the substrate 15 having one end surface fixed to the inner surface 7 of the door 3.

  In the hinge device 20 of this embodiment, the length of the fixed member 21 from the substrate 10 to the tip of the cylindrical portion 22 of the support part 11 is about 50 mm, and the outer diameter of the bolt 24 of the fixed member 21 is The length of the bolt 24 is 100 mm, and the inner diameter of the receiving hole 26 is 5.2 mm. Further, the outer diameter of the shaft pin 16 of the rotation side member 8 is 5.0 mm.

As a result, the substrate 15 of the rotation-side member 8 is rotatably supported on the upper surface of the head 25 of the bolt 24 of the fixed-side member 21 around the axis pin 16 as the rotation center.

  The vertical position of the rotating member 8 fixed to the door 3 with respect to the fixed member 21 fixed to the housing 1 is adjusted by changing the screwing amount of the bolt 24 into the through hole 23 as described above. It is possible. Therefore, the vertical position of the door 3 with respect to the housing 1 can be easily adjusted while the door 3 is attached to the housing 1 via the hinge device 20.

  Therefore, even after the door 3 is attached to the housing 1, even if the vertical positional relationship of the door 3 with respect to the housing 1 is shifted, the door 3 is attached to the housing 1 while the door 3 is attached to the housing 1. The misalignment can be easily eliminated by adjusting the vertical positional relationship with respect to.

  The present invention is not limited to the embodiment described above. As shown in FIG. 5, in the large casing 1, the opening 2 is also large. Therefore, the size of the door 3 for opening and closing the opening 2 is also increased. In this case, the door 3 is attached to the housing 1 by a plurality of hinge devices. It is also possible to employ the hinge device 20 of the embodiment only for the uppermost hinge device of the plurality of hinge devices, and to employ the conventional hinge device 4 for the other hinge devices.

  In this case, the weight of the door 3 is supported only by the hinge device 20 of the uppermost embodiment, and the adjustment of the vertical positional relationship of the door 3 with respect to the housing 1 is performed only by the hinge device 20 of the uppermost embodiment. That is, in the conventional hinge device 4 located below the hinge device 20 of the embodiment, in FIG. 8, the lower surface of the substrate 15 of the rotation-side member 8 is in a state where the shaft pin 16 is inserted into the through hole 13. The mounting position of the rotating side member 8 with respect to the door 3 of the substrate 15 is set such that a gap is intentionally generated between the rotating side member 8 and the upper surface 14 of the cylindrical portion 12 of the fixed side member 6. Therefore, the conventional hinge device 4 located below the hinge device 20 of the embodiment has only a function of restricting the rotation position (range) of the door 3 in the horizontal plane.

  Further, as shown in FIG. 6, it is also possible to employ a substrate 15a formed by bending a single metal plate so as to enclose the shaft pin 16a in the rotating member 8a fixed to the inner surface 7 of the door 3. .
